Captain,
Clark Gable323rd Bomb, Squadron, 91st Bomb Group (The "Eight Ball)
(Actor)Captain, US Army Air Corps. Although
beyond draft age, Clark Gable enlisted as a private in the Air Corps
on Aug. 12, 1942 at Los Angeles. He attended Officers' Candidate
School at Miami Beach and graduated as a second lieutenant. He then
attended aerial gunnery school and in Feb. 1943, on personal orders
from Gen. Arnold, went to England to make a motion picture of aerial
gunners in action. He was assigned to the 351st Bomb Group at
Polebrook and although neither ordered nor expected to do so, flew
operational missions over Europe in B-17s to obtain the combat film
footage he believed was required for producing the movie entitled
"Combat America." Gable returned to the U.S. in Oct. 1943
and was relieved from active duty as a major on Jun. 12, 1944 at his
own request, since he was over age for combat.

NOTE:
After the death of his wife, Clark Gable enlisted in the Army Air
Corps as a 41-year-old lowly private (though a private that had his
uniforms tailored by the MGM costume department). During his tour of
duty, Gable filmed German military installations for U.S. Army
Intelligence, which led field marshal Hermann Goering to put a price
on his head. It was never collected.

Stewart was the first Hollywood celeb to enter the service for World
War II. Though initially refused entry into the air force because he
was underweight, Stewart talked the recruitment officer into admitting
him. He would fly 20 combat missions as a B-24 Pilot in Europe and
command a squadron, eventually earning the rank of colonel, as well as
the Air Medal, the Distinguished Flying Cross, the Croix de Guerre and
seven battle stars. After the war, Stewart continued in the U.S. Air
Force Reserve and became a brigadier general, the highest-ranking
entertainer in the American military.
